Analox specialise in monitoring gases including oxygen, carbon dioxide and nitrogen, but we do cater to some of the more unusual gases too. One of these gases is argon. What is Argon? Argon (Ar) is a ...

Fine chemicals are used as active ingredients or additives in the pharmaceutical and food & beverages industries, as well as in agriculture. The cracking of raw materials such as light virgin naphtha or liquefied gas results in intermediate products (ethylene, hydrogen, methane, CO2). At the end of the process chain, these can provide highly pure materials such as niacin (vitamin B3) or ...

THIOPAQ® is a biotechnological process to remove H2S from refinery gases to produce elementary sulfur. In the autumn of 1999, the first THIOPAQ® process was licensed to the refinery industry for the removal and recovery of sulfur from several streams within the Alexandria Minerals Oil Company (AMOC, Egypt) grass-roots dewaxing complex. A hydrotreater offgas stream, amine regeneration gas and a ...

Leman Instruments is a leading European company, specialised in standard products, OEMs and in custom designed realisations involving high purity H2, N2, zero air, combined solutions for FIDs, GCs, purge air generators, CH4 & CO2 scrubbers, N2 and multigas for LCMS with high level of communications involving Ethernet, USB, RS 485 and ...

Hydrogen generators are now becoming an essential component in many laboratories with greater gas consumption levels. Generators are considered to be preferable to cylinders, particularly because of the safety concerns about having high pressure hydrogen in the laboratory working environment. Hydrogen generator systems typically produce Hydrogen with a two-phase system. Hydrogen is first ...

With several beneficial attributes that make it a good blending agent in gasoline, butanol continues to hold promise for use as a biofuel. It is compatible with existing vehicles and refueling infrastructure. Low vapor pressure, high octane number and favorable distillation properties all add to the high blending value of butanol. Now, a new ASTM International standard will be used in isobutanol ...

Fourteen new energy-efficient and environmentally acceptable catalytic processes have been identified that can use excess high-purity carbon dioxide as a raw material available in a chemical production complex. The complex in the lower Mississippi River Corridor was used to show how these new plants could be integrated into this existing infrastructure using the chemical complex analysis system. ...

Introduction Infrared spectroscopy offers many unique advantages for measurements within an industrial environment. Historically, the technique has been used for a broad range of applications from the composition of gas and liquid mixtures to the analysis of trace components for gas purity analysis. In cases where a well-defined method of analysis is involved, such as the measurement of ...

Indoor Air Quality (IAQ) refers to the degree of air purity inside buildings that constitute the usual environment in which people carry out activities (offices, homes, schools, shopping and leisure centres, etc.) Because of increasing urbanisation and our contemporary lifestyle, most people spend a large proportion of their time in these closed environments. The high level of atmospheric ...
